I wish there was some tools like Unity animation panel or Behavior Tree plugin in Unity.

Tools that would integrate well with any code in JS. Maybe you would define blocks with code, and wire the things up in the IDE but with a graphical interface. Kind of like how draw.io is integrated in Jetbrains IDE (and certainly in VSCode too).

Unrelated to javascript, but in the robotics industry there is a trend towards Behaviour Trees. https://www.behaviortree.dev/ is a C++ library that was originally designed for controlling robots via ROS, but it appears to be decoupled from the ROS ecosystem so it could be used for other projects.

There is a basic UI available for editing the tree https://github.com/BehaviorTree/Groot
